and field properties.

Queries – Allows the retrieval of information from groups of tables and process the information. Queries can
combine data from different tables and update multiple tables. Queries allow you to work with only a group of
specific records from one or more than one tables.
Create a query by specifying the input tables/queries,
field names, filers, and sorting/grouping properties.
The wizard asks you questions and creates a query
based on your answers.
Forms – A visually appealing way to put information into a table. It is often more efficient to use a form instead of
a table because a form simplifies data entry or viewing.
Create a form by specifying the record source,
controls, and control properties.
The wizard asks questions and creates a form based on
your answers.
Reports – Allows the printing of a summary of data from a table or query into a formatted document.
Create a report by specifying the record source,
controls, and control properties.
The wizard asks questions and creates a report based
on your answers.
Relationships - can be used to link two or more tables that share a field being used in one table as a primary key.
The tables can relate and can be used in queries and forms. In order to relate tables you must first click on the
Relationships button
on the toolbar and select tables to which you wish to relate. Click Close and the
Relationships window will be displayed.

Drag the primary key field from one table to the equivalent field in another table to relate 2 tables. Close the
